Zetta 138 SUP Pump

Hi Shirley,

We truly value the concerns you’ve raised, and we’ve discussed them thoroughly with our team before replying.

Your first inflation going smoothly is a positive sign that the unit is functioning correctly. What you experienced during the second use is in line with its normal operation. For a 19 PSI SUP, which is on the larger side, one full battery charge typically supports about 1–2 complete inflations.

It’s normal for the pump to feel warm after use, especially when inflating to higher PSI levels, as it operates under a high load — similar to many electronic devices. That said, we completely understand this may be concerning, and we’re continuously working on ways to improve this experience, including exploring better heat-dissipation designs and insulating materials. For now, we recommend allowing the pump to cool for about 5 minutes before using it again, which helps protect the motor and extend its lifespan.
